Nike Fuelband
Simply tracking your activity can be a good way to motivate yourself to do
more. The Nike Fuelband makes that simple: it's a wristband that contains
motion sensors to track your movement through the day, translating your
activity into 'Nike Fuel' points that aim to let you compare yourself to
others, regardless of the sports you're doing. It also counts the steps you
take - 10,000 per day is seen as a good indicator of a healthy lifestyle -
and tells the time. It comes in three colours but the sleek black version is
the coolest.
